Document Type and Number:
WIPO Patent Application WO/2010/143364
Kind Code:
A1
Abstract:
Provided is a technology by which an area can be flexibly partitioned and managed regardless of the capacity of a storage device, and an area can effectively utilized by an effective method when a file is allocated to a partition.
A size of a partition of a storage device is expressed by a sum of mutually different power of twos, and when an area having a size of each of the power of twos constituting the sum defines a main section, each main section is divided into sections having sizes obtained by sequentially halving the main section, and an allocation table which stores allocation information indicating the file allocation status with respect to each of the sections having respective sizes including the main section is generated. The partitions are managed on the basis of the allocation information stored in the allocation table.
